What if the 18650 lithium battery fails to charge?

Why does 18650 lithium batteries not filling into electricity?

The type 18650 lithium electricity is more commonly used in electronic products lithium battery and in the laptop battery as the batteries in use.Found that sometimes when we use 18650 lithium battery charge it into electricity, let's look at the reasons.

1. Battery electrode contact smudgy, contact resistance is too large to cause the pressure drop is too large, to have full and stop charging charging host;

2. Internal charging circuit malfunction, can't normal charge;

3.18650 the lithium battery internal fault occurs.

18650 battery not filling into electrical solutions

1, the charger interface aging or damage to the charger itself change the new charger test.

2, causing poor contact, charging hole metal oxidation belongs to a hardware failure, need to contact close examination after-sales maintenance.

3, charging line quality has a problem, change the new line.

4, life already made or damage to the battery itself, can be directly replace the battery.

18650 lithium battery repair principle

Restoration theory a

Long time use of the metal surface of lithium-ion batteries will have a certain degree of oxidation, mobile phone battery with phone contact is bad, lithium-ion batteries use time shorter, and use a rubber polishing or other clean tool can erase rust on the surface of the material, let the battery and mobile phone contact.

Repair the principle of two

Low temperature can make internal lithium battery electrolyte change, promote cells react on the frozen.The use of lithium-ion batteries is actually a charge and discharge process.During this period, the battery inside the negatively charged and positive charge/hit each other.The battery will be more and more not after use, because in normal room temperature, the inside of the electronic kinetic energy is larger, so the battery is in active state, relatively frequent leakage situation.And put the lithium battery in low temperature environment, the lithium battery of lithium and electrolyte membrane on the surface of the microstructure, as well as their interface will change significantly, causing the battery internal temporary is not active, to reduce leakage current.So after recharging, cell phones for electricity will increase the time.

About 600 times the cycle of lithium battery service life.If you charge more, hot games make its internal molecules arranged microstructure gradually destroyed, storage charge efficiency will decrease gradually.And "freezing process is easy to damage the internal structure of the original battery, a short period of time may increase the ability to take charge, but long-term use may not be effective.", lithium battery in the microstructure of once destroyed, it is impossible to completely recover again, long-term use of this method accelerates the wastage of the mobile phone battery.

Repair principle of three

To depth discharge of mobile phones, is by running out of internal power, to achieve a deeper level of recharging, the need to adopt some unconventional methods.Find ways to mobile phone connected to a 1.5 V small bulbs, lithium battery internal power will transfer to the small bulbs, until all light."Mobile phone through low voltage slowly run out of electricity.Under normal circumstances, if the phone after connect is lower than the rated voltage of 3.6 v, will automatically power off."After put the electric, recharging of mobile phone batteries can be used for a longer time.

18650 lithium battery repair methods

1, will your battery all after use, with the temperature, battery under the condition of the temperature instability will greatly shorten the using time, because the battery is without electricity and quite a number of lithium ion has a power in this way can make the memory electric release part of the winter, on the outside for a while, it to the house again.

2, there is a kind of method, remove the battery, put a week or so, the consumption of electricity will slowly, need to use the machine will first electricity consumption after completely.Then all rushed, estimate you charging time is very short, now filled with, disconnect again, again and again several times, absolutely effective.
